| Abstract(in English) | Recently, wireless many-to-one networks have been attracting much attention and wireless sensor ad-hoc networks are applied to various applications. In ad-hoc networks using Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA), the capacity is drastically decreased by the hidden node problem. In this paper, we assume a many-to-one network and propose a transmit power control (TPC) algorithm to avoid the hidden node problem. In our proposed TPC algorithm, 1-hop area, forced multi-hop area, and multi-hop area are defined. All nodes in the 1-hop area adjust their transmit power as they can sense each other's transmit data, and all nodes in the forced multi-hop area and multi-hop area control their transmit power as they connect to a gateway (GW) with multi-hop and reduce the interference to nodes in 1-hop area. The network capacity using the proposed TPC algorithm is evaluated by a computer simulation. By this computer simulation, it is shown that the network capacity of TPC is better by about 2.8 times than that of No-TPC. |
